WILLIAM H. IVIGCONNELL, OF HARLAN, IOWA.

COMBINATION ROLLER AND SCRAPER.

To all whom it may concern:

Be it known that I, IVILLIAM H. MoCoN- NELL, a citizen of the UnitedStates, residing at Harlan, in the county of Shelby and State of Iowa,have invented certain new and useful Improvements in Combination Rollersand Scrapers, of which the following is a specification.

This invention relates to improvements in a combination roller andscraper of the class adapted for use in road-working and as anagricultural implement.

The object of the invention is to provide a machine which will beeffective, when moved forwardly, for scraping or leveling the soil of aroad bed and will roll the soil after it is thus evened or leveled, andwhich by reason of certain devices employed, may be convenientlyadjusted to operate as a roller for field use to smooth lumpy ground, orthe like.

The novel features of the invention are fully described herein, pointedout by the appended claim and illustrated in the accompanying drawing,it being understood that changes in form, size or proportion may bemade, within the scope of the claims, without departing from the spiritof the invention or sacrificing any of its advantages.

In the drawing Figure 1 is a plan view of a combined roller and scraperembodying my invention. Fig. 2 is a view of the same in longitudinalsection, on line a a of Fig. 1. Fig. 3 is a detail relating to themounting of the wheels.

Referring now to the drawing for a more particular description numeral 3indicates a frame comprising parallel, supporting end-plates 4 and 5, arear cross-plate 6 secured at its ends to the rear ends of plates 4 and5 and disposed, substantially, at right angles thereto, a scraper-bar 7being secured upon the front ends of end-plates 4 and 5. The frame thusprovided is rectangular in form, except the front end which extendsdiagonally from one end-plate to the other, end-plate 4 being longerthan end-plate 5; and scraper-bar 7, while extending transversely, isdisposed diagonally from the longer to the shorter end of the frame.

I provide platform 8 having parallel ends, its rear edge being parallelwith cross-plate 6 and terminating short thereof, to provide arectangular opening or recess 9 near the rear part of the machine, itsfront edge or side 10 being seated upon the scraper-bar.

Specification of Letters Patent.

Application filed May 5, 1909.

Serial No. 494,090.

Within recess 9 is disposed the cylindrical roller 11, its shaft 12being seated in suitable boxing 13 upon end plates 4 and 5. At 14 areshown clevises or screw-eyes, these being secured near the ends of bar7, to project at the front of the machine. A pullring is shown at 15 atthe front and midway between the ends of the machine; andconnecting-rods may extend between this ring and the screw-eyes.

Scraper-bar 7 is inclined upwardly and forwardly from its lower,flattened side or edge 17 to the platform, this particular part of thescraper-bar being formed with a broad contact-surface disposed parallelwith the platform, its wide surface being useful to prevent an undueengagement of the soil. Said scraper-bar may have the longitudinal shoeor contact-bar 18 secured thereon, said bar having a tapered orsharpened longitudinal ridge 18 formed to extend forwardly thereon, saidridge having a lower surface 38 disposed in the same plane with edge 17of bar 7;

As thus described the machine or implement may be used to advantage as ascraper and roller for work upon road beds, and when moved forwardly thescraper-bar and contact-bar will engage the surface of the soil; onaccount of the upward and forward inclination of the scraper-bar, asdescribed and on account of the flattened surfaces mentioned of bars 7and 18, only a limited quantity of soil will be engaged; and on accountof the angular disposition of the scraper, the machine will operate toconvey accumulations toward its shorter end; and when in use as a roadimplement, the shorter end of the machine is disposed at or near themiddle of the roadway, so that accumulations will be moved in thatdirection.

I provide the longitudinal scraper or blade 19, having its ends 20mounted pivotally in brackets or bearings 21, secured upon cross-plates6, and as a control for causing the blade to engage the periphery of theroller, for the purpose of removal of adhering soil, I employ arm 22,said arm being secured at its lower end upon and midway of the ends ofthe blade. I provide the bracket 23, mounted upon the platform. At 241upon the bracket is mounted the rocklever 25, comprising arm or treadle26 and arm 27. I employ link 28 connecting pivotally between the upperend of arm 22 and arm 27 of the rock-lever.

Arm 26 of the rock-lever is engaged by spring 29, this spring beingsecured to the platform; the engagement of the spring with said armcauses blade 19 to remain 5 normally out of contact with the surface ofthe roller. When it is desired to move adhering soil from the roller, adownward movement of the treadle may be madeto cause an engagement ofthe blade with the surface of the roller. At is shown a 'drivers seatsuitably supported upon bars 31, the latter being secured to the frameto overhang the roller, and at 31 is shown a guard-rail.

I provide wheels 32 having axles 33 -mounted at the opposite ends andnear the front of the machine, and thereby the scraper-bar may be raisedso that, during the forward movement of the machine, said 2 scraper-barwill not engage the soil, whereby the implement may be used as a rollerto level or harden the ground in a field this being useful in someinstances Where crops have been planted, and by oroviding means 25 forvertical adjustment 0 the axles, the scraper-bar may be under control sothat it may be disposed closely adjacent to the soil, this feature beinguseful for many purposes.

The wheels at all times limit the downward movement of the scraper andprevent said scraper from entering the soil beyond a predetermineddegree. In some cases however, the roadway may be so hard as to supportthe scraper in such a position that the wheels will not come intoaction.

The wheels may be mounted in openings 39, formed in the ends of platform8. As a means for vertical adjustment of the wheels, a housing or casing34c may be provided for the axles, having a transverse, threadedwrist-pin 35; threaded washers or nuts 36 may be employed for thesepins, one being seated below and the other above plate 37, said platebeing secured upon the platform, whereby the platform may be disposed ata desired altitude above the axles, and the scraper-bar will be undercontrol to be elevated or lowered.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is,-

A combined roller and scraper comprising a supporting frame, a roadroller supporting the rear of said frame, a scraper bar diagonallyarranged across the front of said supporting frame, and means for adjustably supporting the front of said frame and said scraper bar, saidmeans comprising ground wheels and axles therefor, housings in whichsaid axles are mounted, threaded vertical stems projecting from saidhousings through a portion of said frame, and members threaded upon saidstems for locking them in their adjusted positions.-

In testimony whereof I have affixed my signature in presence of twowitnesses.
